| Zusammenfassung: | An electromagnetic noise absorber to be attached around an electric cable to attenuate noise transmitted through the electric cable. The electromagnetic noise absorber comprises a strip-like base material and a plurality of ferrite pieces fixed to the strip-like base material. The plurality of ferrite pieces are formed by fixing a sheeted ferrite sintered body to the strip-like base material, and subsequently splitting the sheeted ferrite sintered body along split lines oblique with respect to a longitudinal direction of the strip-like base material. The electromagnetic noise absorber is wound around a circumference of the electric cable such that the split lines are parallel to an axial direction of the electric cable, thereby being attached in a spiral manner around the circumference of the electric cable. |
